Why can't reciprocating ammonia compressor use copper-containing materials?

Why can't reciprocating ammonia compressor use copper-containing materials?
1. Chemical reaction corrosion: Ammonia gas will react chemically with copper and copper alloys to generate brittle copper salts, which will cause corrosion and damage of parts.
2. Initiation of cracking and leakage: The reaction products can easily lead to embrittlement and crack of copper parts, destroy the sealing structure and cause ammonia gas leakage.
3. There are potential safety hazards: ammonia is toxic and flammable, and the corrosion failure of copper will greatly increase the production safety risks such as poisoning and explosion.
